Question

what you know the metric system 1. identify how many places you would need to move the decimal to convert. candela to kilocandela a: kilomole to decimole b: milligrams to kilograms c:

Explanation:

Step1: Recall metric - prefix conversion

1 kilocandela (kcd) = 1000 candela (cd), so to convert from candela to kilocandela, we divide by 1000. Moving the decimal 3 places to the left.

Step2: Recall mole - prefix conversion

1 kilomole (kmol) = 1000 moles and 1 decimole (dmol)=0.1 moles. So 1 kmol = 10000 dmol. Moving the decimal 4 places to the right to convert from kmol to dmol.

Step3: Recall mass - prefix conversion

1 kilogram (kg)=1000000 milligrams (mg). To convert from mg to kg, we divide by 1000000. Moving the decimal 6 places to the left.

Answer:

A: 3 (move decimal 3 places left)
B: 4 (move decimal 4 places right)
C: 6 (move decimal 6 places left)
